if i'm not mistaken, this is possible... but its matter of begin testing...

> dhcp-host=02:00:0A:00:00:00,net:foo-range,host1,192.168.0.1,static
> dhcp-host=02:00:0A:00:10:00,net:bar-range,host2,192.168.1.1,static

> So what I would have is that host1 would get the fqdn host1.foo and the 192.168.0.1 address, while host2 would be host2.bar and get the 192.168.1.1 address.
